To all whomitmy concern: 7

Be it known that I, JOHN Q. SHERMAN, a citizen of the'United States, and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented preferably by a sprocket feed or other self' alining feed over the writing tablet, and in which one of said strips is wound up or otherwise positively accumulated within the casing of the machine after the feeding opera-" tion. The invention has an applicatlon, how-.

ever, to any autographic register of the record type.

It has as its object the provision of meansv whereby the device which accumulates the said retained strip is prevented from exertmg any strain on the same, during a portion of the feeding operation.

In general, the difiiculty with feeding a record strip along with the remainder of the strips in autographic registers, is that the rewind for the record strip conflicts with th feed of said strip.

In autographic registers of the prior art it has furthermore been developed that where a plurality of strips of paper are fed by means of sprockets engaging in marginal perforations, there must be no strain on the various films during a portion at least of the feed so that there may be an automatic-adjustment of the sprocket pins and perforations. To remedy this, I have found that if at some one period durin the feed there is no strain on the strips or lm' of paper, the feed of the paper will not conflict with the record winding device and the pins will accurately aline the perforations.

In machines which retain one of the plurality of strips for a record, there has hitherto been developed no means of winding up.

the record strip, which does not exert a constant pull on said strip, thereb exerting a strain on it during the feed. 11 my'invention this defect of the prior art is done away with, and I accomplish this object, and other advantages to be noted by that certain construction and arrangement of parts to be "where they are torn off.

claimed.

. In the drawings,

Figure- 1 is a detail elevation of the feeding hereinafter more specifically pointed out and and" record strip storing means mounted on and in the casing of an automatic register.

Fig. 2 is a like view showing the same parts I in a different position.

Fig, 3 is a top plan view of a machine made I according to my invention, with the lid removed and the hingeddoor open.

The specific type of casing shown in the drawings is no part of my invention, and is selected for purposes of illustration only.

. There is shown the casing 1,having the top lid 2 and the hinged door 3, which gives access to the portion of the casing lying beyond the feeding devices. The feeding devices byme although any type of feed could be .nsed.' They comprise rotary members 4 havmg the pins 5, which pins engage in marginalperforations 6 in the paper strips 7.

One of the strips, the strip 7, which is re tained within the casing for a permanent record of all transactions is led downwardly after it passes the sprocketor pin feeding devices and is wound on to a roll or core' onshown in the drawings are the ones preferred the shaft 8. The balance of the strips are led out of the opening left at the endof the lid, I

1 Although no printing'is shown upon the strips it will be understood that normally they will be-printed up in sections of the length that will be fed out of the inachine in one complete operation of whatever feed device is used, each of the strips having like printing and having its perforations arranged in like relation to the printing where sprockets are used.

The pin bearing bodies are mounted on a shaft 9 which is rotated by a handle 10, and

preferably on' the outside of the machineagainst sudden stoppage of the pulley 14, but also allows it to slip on either or both pulleys so as never to exert a force on the storage roll which would tear the film of paper that is being wound thereon.

In addition to the pulley 11, the main shaft 9 of the operating device has a cam '16 thereon. Mounted between the shaft ,9 and the pinion 13, is a bracket piece 17 in which is slidably held a plunger 18, The plunger is held by means of a coiled spring 19, in contact at its one end with the edge of the cam. The other end of the plunger is pointed, and lies adjacent the ratchet wheel 20 on th'epulley 14. The parts are so proportioned that when the plunger rides up on the nose 21 of the cam 16, its pointed end will come into mesh with the teeth of the ratchet pinion 20, and thus stop entirely the drive of the storage roll.

As shown in Fig. 1 the parts in position as preferably set, which is assumed just before the end of the feed. The plunger is in position in mesh with the ratchet 20, and the paper is accumulating between the feeding device and the storage roll. After the next operation has begun, however, as shown in Fig 2, the plunger will ride over the nose on the cam, and be spring forced out of mesh with the ratchet,

allowing the storage roll to be operated.

The freedom from strain of the record strip or film is thus provided for, by my device, at the desired point during each operation giving the opportunity to the sprocket feeding device to aline the record strip with the rest of the duplicates.

The spring belt is valuable as accommodating'itselfto the strain resulting from the stoppage of the driven element and'also provides for the slippage which is required where the storage roll has assumed large diameter from accumulated paper. As is well known in the autographic register art, there must be provided some means for taking care of the changing diameter of the storage roll, and so far as l am informed, this spring belt is an entirely novel wayof providing the necessary function to the record roll drive. The proportionate size of the pulleys over which the belt runs'can, of course, be varied, it being the intent in the drawings to show the pulley l l as of smaller size than the pulley 11 I thus provide-by my invention not only a friction drive for the storage roll but an intermittent and resilient drive as well, due to the stoppage of the roll and the spring belt which forms the driving connection.

' reac es As a substitute for the spring belt in providin an extendible drivlng member some belt tightener device could be employed such as an idler pulley for the belt, provided with a resilient mounting. As such devices are well known specific illustration is not believed to be necessary.

it do not desire to be limited in the claims that follow to any specific structure, where the same is not clearly called" for, as I desire the full application of the doctrine of equivalents in their construction.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In an Jautographic register, the combination with a feeding device for a plurality of paper strips including a record strip, of a storage roll for the record strip, and means for connecting said storage roll and the sprocket feeding device, comprising in part, an extendible belt, together with a stop for the storage roll for inhibiting its continuous movement with the sprocket feeding'device.

2. lln an autographic register, the combination with a feeding device for a plurality of paper strips including a record strip, of

a storage roll for the record strip, and means for connecting said storage roll and the feeding device, comprising in part, an extendible belt and a movable member for stopping the storage roll from movement, and a cam on the feeding device for operating said movable member. I

3. In an autogr'aphic register, the combination with afeeding device for aplurality of paper strips including a record strip, of

a storage roll for the record strip and means connecting said storage roll and the feeding device, comprising in part, an extendible belt formed of an endless spiral spring, and a movable member for stopping the storage roll from, movement, and a cam on the feeding device for operating said member.

4. In an autographic register the combination with a shaft having feeding means for a plurality of strips of paper connected thereto, a pulley on said shaft, and a cam on said shaft, a storage roll in the machine for retaining therein a record strip, a pulley on said roll, a spring belt passing over two pulleys, a plunger adapted to positively stop the movement of the storage roll, said shaft for the feedin means having a cam thereon against which the plunger rides,

said cam being adapted to force the plunger into locking Fosition during a portion of the movement 0 said shaft.
